Which sentence describes the action of natural selection? An ecosystem contains two types of giraffes, some with short necks and

others with long necks. The distribution of this trait is equal among the population. A disease causes low-lying shrubs to die out. The long-necked giraffes can access more food, so they have a better chance of surviving to reproductive age. After several generations, all the giraffes have long necks.
ANSWER: The long-necked giraffes can access more food, so they have a better chance of surviving to reproductive age.

Answer: The long-necked giraffes can access more food, so they have a better chance of surviving to reproductive age.

Explanation:

Natural selection is the process of differential survival and further facilitate in reproduction. Here, the organisms which have suitable phenotypic traits exhibit better chances of survival and reproduction over others.  

According to the given situation, the long-necked giraffes will be able to fetch more food than short necked giraffe. As they have phenotypic advantage of long neck which will help them to reach long tree canopy. They will derive food and hence, their chances of survival and reproduction will be more than the short necked giraffes.

pickupchik [31]
The examples of species changing over time are statements A, C, and D.

All these changes, such as new types of squash was developed in the garden. weeds evolution to resist chemicals, and the changes in butterflies wing pattern over the years is because of Mutation. Obviously, rabbit's ears are always bigger than mice and Giraffe's neck is always longer than the deer's. In genetics, mutation is the process of permanent alternation of the nucleotide sequence in DNAs.

mote1985 [20]

Answer:

D

an increase in the length of the fatty acid tails.

Explanation:

As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated

and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and

decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and

more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity
